[On the clinical treatment of rectal carcinoma]

From 1975 to 1986, 478 operations were performed on the patients with rectal carcinomas. Radical resection rate is 63.4%. We have studied the metastatic law of rectal tumors through lymph-duct, reverse invasion in wall, radiation and the hot-therapy before the operation. Extended lymph nodes resection were performed. The Dukes C 5 years survival rate was increased from 32.6 to 79.2 percent. Our results suggested that (1) local colorectal and rectal tract should be resected sufficiently. The operation of remaining anus should be based on sufficient radical resection. (2) Extended radical resection include the third stationary lymph nodes. The lateral lymph nodes should also be removed in association with tumor under the peritoneal reflection. (3) If hepatic metastasis was accompanied, the metastatic site should be removed as well as primary site. (4) In the case of late stage, palliative operation was performed. (5) As soon as the rectal tumor recur, the second operation will be administered. In the meanwhile, we suggested, in order to maximum increase 5 years survival rate, that multi-measures were adopted.
